BATTERY CHARGING FOR ADVANCED SUBMARINES

摘要

In the last decades, the political map of the world has transformed significantly, altering the tasks of navies worldwide. With new assignments, the requirements for naval platforms, including submarines, have changed and are likely to continue to do so in the near future. Submarine size, for example, has increased due to longer transit distances to operational areas as well as to accommodate various Air Independent Propulsion technologies into the hull. Despite hydrodynamic improvements of the hull shapes, the larger displacements have led to higher power demands.This trend for more power will be even further accelerated by new Li-Ion battery technologies, which are going to increase underwater endurance and performance of submarines significantly. However, the diesel engine driven charging unit technology needs to adapt to the new requirements: firstly, more electrical power and secondly, provide rated power almost the entire operational time to fully utilize the Li-Ion advantages.
